Grid Middleware, programming Grids, gLite, EGEE
The past few years have seen the creation of the first production level Grid infrastructures that offer their users a dependable service at an unprecedented scale. Depending on the flavor of middleware services these infrastructures deploy (for instance Condor, gLite, Globus, UNICORE, to name only a few) different interfaces to program the Grid infrastructures are provided. Despite ongoing efforts to standardize Grid service interfaces, there are still significant differences in how applications can interface to a Grid infrastructure. In this paper we describe the middleware (gLite) and services deployed on the EGEE Grid infrastructure and explain how application scan interface to them.
